Dear Colleagues

We need to discuss plans for the beam tests and this is quite urgent. We are going to use a similar type of 20 cm x 10 cm x 45-x cm module as LFHCAL, so again it makes sense to coordinate with them. Please respond quickly if you have any suggestions.

In order to make those beam tests happen, we can probably reuse one of the existing LFHCAL modules and put our tile+absorber configuration. I see they are going to perform a lot of tests at CERN PS/SPS.

At some point it may be good to perform a combined HCal+EMCal test.

This was my initial idea to cover any possible type of particle/need:

1. Protons 0.3-20 GeV

• Needed to test hadronic interactions at high energy and response at low energy, which is different than neutrons

• 2025-2026 prototype tests
• 2026-2027 first article tests

Pions 0.3-20 GeV

• Needed to study e/h response
• 2025-2026 prototype tests
• 2026-2027 first article tests

Electrons 0.3-20 GeV

• Needed to study e/h response
• 2025-2026 prototype tests
• 2026-2027 first article tests

Neutrons 0.1-1 GeV ?

• Unmoderated from spallation source
• Needed to validate the low energy neutron detection performance – main goal
• 2025-2026 prototype tests
• 2026-2027 first article tests
